Pathologic Gait Flashcards
What are potential causes of altered gait?
Pain
Past injury - spinal learning and reeducation of motor patterns
Peripheral sensory loss
LMNL (loss of tone with weakness)
UMNL (increased tone with weakness)
What is the cause of a Trendelenberg gait?
Weak gluteus medius or lateral hip stabilizer
What does a Trendelenberg gait look like?
Hip translates laterally while weight bearing on the involved side
What peripheral nerve is likely affected in a patient with Trendelenberg gait?
Superior gluteal nerve
What nerve root is likely affected in a patient with Trendelenberg gait?
L5
What muscles are likely affected in a patient with Trendelenberg gait?
Gluteus medius or lateral hip stabilizers
What does a gluteus medius lurch look like?
Torso leans laterally over the affected hip when weight bearing with significant pain and paralysis of the gluteus medius or lateral hip stabilizers
What muscles are affected in a patient with a gluteus medius lurch?
Gluteus medius or lateral hip stabilizers
What peripheral nerve is likely affected in a patient with a gluteus medius lurch?
Superior gluteal nerve
What nerve root is likely affected in a patient with a gluteus medius lurch?
L5
What does a gluteus maximus lurch look like?
Lack of leg extension during gait with the torso extending and rotating ipsilaterally while weight bearing on the involved side
What peripheral nerve is likely affected in a patient with a gluteus maximus lurch?
Inferior gluteal nerve
What nerve root is likely affected in a patient with a gluteus maximus lurch?
S1
What are potential causes of a circumduction gait?
Knee fusion, weak quadriceps, spastic paresis (UMNL)
What muscle is likely weak in a patient with a circumduction gait?
Quadriceps
